安装了denyhost 后，，启动服务出现了错误提示能帮看忙一下吗？

salemilk

[root@xxxxx ~]# service denyhosts start
starting DenyHosts:    /usr/bin/env python /usr/bin/denyhosts.py --daemon --config=/usr/share/denyhosts/denyhosts.cfg
DenyHosts could not obtain lock (pid: 1604)
[Errno 17] File exists: '/var/lock/subsys/denyhosts'

该怎马解决啊？？
